Yes I see your point,Like the exapmle I used with the 6800's I too belive that it is very possible the parts must be mass produced in a cost ecinomical way for the developer.I dont see why there still wouldnt be some sort of resistor configuration on the pcb itself like you mention it is simply cheaper,However chips comming off the die vary alot sometimes some that may have one bundle of pipelines damaged say 12 instead of the normal 16 or whatever.The research I have done has showed me amazing differences in one chip made right after the perfect chip.So like you are saying it could be much more cost efective to flip a couple resistors high,and one to ground or whatever the case may be,then asign a bios accordingly to make into high end,mid,or low.If you end up getting a bit more info on that let me know I will start tweaking a few bios's and see if I cant adapt one for an upgrade. Sometomes there's more than one way to skin a cat,let's see if we can find a new one lol :P. Mike.
